Letters Patent No. 73,870, dated January 28, 1868.

IMPROVEMENT IN LAMPS.

(the scene marsh in in time items patent mm mating not at 11p smite.

to ALL WHOMIT MAY CONCERN 7 Be it known that I, ARTHUR W. 'BROWNE, of the'city of Brooklyn, and county of Kin-gs, and State of New York, have invented a certain new and useful Improvement in Lamp-Burners; andI do hereby declare the following to be a full description of the same, reference being bad to the accompanying drawings, which form part of this specification, and in which Figural represents a perspective view of my improved burner looking from above, with the cone and cover removed to show the internal arrangement.

Figure 2 represents a vertical cross-section through the burner, parallel with the wheel-shaft, showing the same apparatus.

Figure3 is also a vertical cross-section through the burner, at right angles to the wheel-shaft, showing the inclining wick-tube, also the auxiliary wick.

Letter A represents the rotating perforated bottom piece with springs-attached; B, the main tube G, the cone; .D, the support forthe wiclctube; E, the cover; F, the wheel-shaft; T, the wick-tube; W, the wheel for turning the shaft; W, the wheels for moving the wick; S, the springs for holding the chimney S, the springs for holding the cone; I, the supports for the cone; K, the wick, and V the auxiliary wick.

Similar letters of reference indicate like parts in the three figures.

The design of this improvement is to make aburner that will not become overheated while lighting, and on which the chimney will remain cool enough to be handled at all times, also .to make a lamp th-at can be easily filled without taking off the burner. The advantages claimed for this improveme nt arethat thelamp will remain cooler while lighting; that it can be quickly filled, with less liability of overflowing, and will maintain an undiminished flame longer than the ordinary burner.

The main tube B is provided on its lower end with a screw, which screws into the collar of the'lamp, and. with a head or projection that supports theperforated. bottom piece A, which is not fastened to, but turns around the tube B, and iskept in its place by the ends of the shaft F, projecting over its inner edge, through holeswhich are diametrically opposite-to each other in the tube-l3, (scefigs. 1 and 2.) 'The centre of the top of thewick-tube T is directly over the centre ofthe opening through the main tube B, but its lower end is inclined from the centre, and is'fastened to the inner side of the tube B by means of the brace D, or by pieces of the tube bent back, (see figs. l and On one of the projecting ends of the shaft F, the toothed wheel W is fastened, the teethof which fit or gear into a circular row of perforations or indentations in the bottom piece A. The wheels W are fastened to the shaft F, and are adjusted in the slots iu-the wick-tube in the ordinary way, (see figs. 1 and The' auxiliary wick V is fastened so as to come in contact with the wick K, just as it enters the bottom of the wick-tube T, (see fig. The s ings S are fastened to or are part of the bottom piece A, and project downwards from its upper and outer eoge, and arebent up at their lower extremities to form a support for the chimney. "he springs S" and supports I are fastened-to or are part of the cover E. The ends of the springs S are bent-up and fit into notches in the edge of the cone.

Having thus described the construction of my improvement, I will now proceed to describe its operations. When the lamp is to be filled, the cone 0 and cover E are removed, which leaves the opening through the tube B clear, the inclination of the tube throwing the wick to one side out of the way, (see fig. 3,) which makes filling an easy operation. After the lamp is filled, the cover E is replaced, and the wick trimmed and lighted. The cone O is then placed in position, and pressed down between the ends of the springs S until it rests on the points of the supports 1. The chimney, which has a cylindrical base, is placed over and pressed down outsiderhe springs S, until it reachestheir bent-up ends. The wick is'adjusted by turning the bottom piece A around the tube B, which is held stationary. The wheel Wbeing ingear with the moving piece A, is caused to rotate, thereby turning the shaft F and wheels W, which lift the wick up and down, as the case may be. The auxiliary wick V aids in lifting the oil when it has burned low, thus maintaining the flame for a longer period than where the unaided wick is used. l

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The inclining tube T, in combination with the central shaft F, wheel W, and rotating'bottom piece, arranged in the manner and for the purpose substantially as described.

2. In combination with the inclining tube '1, the central opening through the tube 13, for the purpose of facilitating the filling of the lamp.
